Surveillance Cameras are widely used by security agencies, corporate, agencies such as the FBI, shopping malls etc. Surveillance Cameras are used basically for keeping an internal check on employees in any organization, tracking down criminals by the security agencies etc. Surveillance Cameras are available and are availed by all companies, firms, organizations having a number of employees. Surveillance Cameras provide adequate checks over the employees, criminals and other people on whom a check is necessary.

Each surveillance camera in the entire security network is assigned a unique angle and identity through a name or a number. The person on whom tabs are being kept is not told about the existence of the surveillance camera. Yet, in most cases the person knows that he is being taped in a surveillance video. It is always better that the fact is kept conceals and is not revealed to the surveillance video subject. In the surveillance network, there is a place where the camera operator sits. It can be called the surveillance camera hub. The intercom operator has a list of cameras connected by the surveillance network.

The surveillance camera operator presses the number of the required camera and its angle and the view on the screen in front of him changes to the camera view required. Surveillance Cameras are definitely not cheaper than other methods of surveillance but are more advantageous in the sense that many different people at difference places can be monitored at the same time. Surveillance Camera systems basically involves setting up of various hubs which are then connected to a main hub. The main hub is called the board. Unlimited number of camera angle changes can be made can be made over the Surveillance Cameras system hub and the calls made are not charged. What is charged from the subscriber is the total subscription fee, What is charged from the subscriber availing the benefits of Surveillance Camera Systems is a monthly charge, which is often quite hefty, but is required with regards to surveillance benefits offered. The fee can be paid monthly or quarterly depending on the liking of the subscriber.

A more recent advancement in the field of Surveillance Cameras is the wireless Surveillance Cameras. Wireless Surveillance Cameras are similar to wired Surveillance Cameras. Wireless Surveillance Cameras are also used for internal and external checks on the subject being monitored. Wireless Surveillance Cameras, like wired Surveillance Cameras allow calls to be made on the intercom network free of cost. Wireless Surveillance Camera systems differ in just one aspect from wired Surveillance Cameras. Wireless Surveillance Cameras systems do not use wires to connect people. Instead they often use satellite signals. Wireless Surveillance Camera Systems do not limit the number of surveillance cameras and new cameras can be added with ease unlike wired Surveillance Cameras. Wireless Surveillance Cameras are quite easier to install also. Wireless Surveillance Cameras can be used over larger geographical areas than wired Surveillance Cameras.

A distinct advantage of this type of surveillance is the production of the Surveillance Video. The Surveillance video can be used to catch criminals red handed. Surveillance Videos also can be used as proof in the court of law for pronouncing a sentence to a person guilty of criminal charges. A more recent advancement in this field has been the invention of the home Surveillance Video system. Any new visitor to the apartment building where Surveillance Video systems have been installed gets recorded in the Surveillance Video system.
